Study On The Construction Of Corporate Image Crisis Knowledge Base Of Ontology

With the continuous development of internet platform and self media, the spread of corporate image in society has become more complex. The very rich dissemination network and the extremely diverse dissemination channel, causes the enterprise image dissemination effect unceasingly to enlarge, the enterprise image can be recognized by the public in very short time. Under such circumstances, the ensuing corporate image crisis has become a major crisis in recent years, but also a major impact on the enterprise crisis. A large number of studies have shown that the occurrence of corporate image crisis is not unexpected, and it often grows and accumulates gradually in the process of enterprise development.Because of the complexity and the dynamic factors of corporate image crisis, the use value of historical experience and data becomes very low, coupled with that a single data semantic expression ability is not strong, the management personnel for the information retrieval efficiency is very low. With the help of ontology knowledge base, it can effectively realize the identification, early warning and decision-making of enterprise image crisis, which is one of the important means for enterprises to avoid the image crisis.This thesis focuses on the establishment of enterprise image crisis ontology knowledge base carry out specific research:First of all, make a detailed study of the knowledge representation of corporate image crisis, and summarize the related concepts of corporate image crisis. In order to protect enterprise image, the construction of crisis ontology has certain standardization and accuracy, and clarifies the basic principles of corporate image crisis constitution construction and put forward the corporate image crisis ontology construction method.After constructing the crisis ontology of enterprise image, the research of ontology reasoning is carried out, and realized the ontology of enterprise image crisis.Based on the construction of enterprise image crisis ontology, this paper puts forward an extended Boolean model based on extended ontology and a model of enterprise image crisis warning. After the ontology based keyword expansion algorithm is proposed, the extended Boolean model is improved according to the characteristics of enterprise image crisis, constructs an extended Boolean model based on extended ontology, and realizes the effective retrieval of enterprise image crisis knowledge. On the basis of proposing an early warning signal extraction algorithm based on enterprise image crisis ontology, constructs the enterprise image crisis early warning model, and finally realizes the warning of enterprise image crisis and potential crisis factors.Finally, this paper analyzes the basic requirements and functions of enterprise image crisis ontology knowledge base management system, and designs and implements enterprise image crisis ontology knowledge base management system.
